"I normally use Crabtree Fan Isolator, but tried this one on my last job and a=was very pleasantly surprised. Almost half the cost of Crabtree, looks great and feels nice to use, simple to wire. The only slight negative is that unlike the Crabtree, doesn't say 'Isolator' on the face. Not a problem for the situation I used it in, but maybe in others where it isn't obvious what the switch is for."
